Checker Plus for Google Calendar is a Google Chrome extension that integrates Google Calendar into your browser. It allows you to see your next meetings and the current date on the icon, get desktop event reminders even in offline mode, add events from the popup in month, week or agenda view without ever opening the Google Calendar webpage. The extension also provides such options as voice notification which enables your reminders or "cooking timers" to yell out "take out the pizza!". You can also gray out past days or highlight weekends, receive reminders of your contacts' birthdays and events, or even add Evite or Facebook events to your Google Calendar when viewing the event's page. Multiple Google Calendars and Google Apps Calendars are also supported. You can find articles on SnapHow, TechThirst, Associated Content, and stadt-bremerhaven, while reviews can be found in the Google Chrome Extensions gallery.
